Classifications

What type of public water system are you?

When it is determined that your facility is going to be permitted as a public water system, the LPA will also classify your water system into one of the following classifications to determine the type of permit required:

Community (CWS): a public water system that serves at least 15 service connections used by yearlong residents or regularly serves at least 25 year long residents of the area served by the system. An example would be a community with residential homes served by a single water system or a mobile home park.

Non-Transient Non-Community (NTNC): a public water system that is not a community water system and that regularly serves at least 25 of the same persons over six months per year. An example would be a school or workplace.

Transient Non-Community (TNC): a non-community water system that does not regularly serve at least 25 of the same persons over six months per year. An example would be a campground, church, or park.

State Small Water System (State Small): a public water system that has 5 to 14 residential service connections, and does not regularly serve potable water to more than 25 individuals for more than 60 days out of the year. An example would be a small residential community with less than 10 homes served by a single water supply.

What type of water supply?

The next step is to determine where you will be getting the water to supply the water system; either ground water or surface water. If your facility is located in the eastern (Palo Verde, Winterhaven, Bard, Colorado River, Pilot Knob, Glamis, etc.) or western (Ocotillo, Salton City, etc.) edges of the county, your available water source will likely be from a ground water well. However, if your facility is located in the agricultural zoned portions of the county (anywhere south of the Salton Sea and between the Westside Main Canal and the East Highline Canal), your facility may have access to either ground water or IID canal water. If your facility decides to use IID canal water, your water system will be characterized as a surface water system.*
